Shortly before announcing its decision to remove H.264 support for HTML5 video from Chrome, Google's codec developers submitted an I-D of its VP8 Data Format and Decoding Guide to the IETF with a request for comments. The document provides a detailed description of the bitstream format and the decoding mechanism used for the VP8 video codec.

Ever since Google announced its purchase of video codec company On2 in August 2009, there's been an expectation that On2's VP8 codec would someday be open-sourced and promoted as a new, open option for HTML5 video. An open VP8 would offer comparable quality to H.264, but without the patent and royalty encumbrances that codec suffers.

Sun Microsystems is setting out to create an open source, royalty-free video codec. Given the considerable head start of well-known, royalty-free video codecs like Dirac and Theora, you might ask why the world needs another. The answer, according to Sun, is the process the company will use to develop it -- starting with a full-on, careful examination of the patent situation.

The announcement of Google's new WebM video format and release of the VP8 video codec as an open standard have been hailed by some as the move that will free the Web from the proprietary H.264 codec widely used for online video today and favored by Apple (AAPL) and Microsoft (MSFT).

Fedora 8's solution is to include Codec Buddy, and point it toward's Fluendo's legal but non-free codecs. At the same time, Codec Buddy opens with a message that "Fedora does not condone the use of audio and video codec that require patent licenses to be written and/or distributed. Due to the existence of such patents,

One week after Google open sourced its $124.6m VP8 video codec, Mozilla and Opera have called for its inclusion in the still-gestating HTML5 specification. As it stands, the HTML5 spec does not specify a video codec. Browser makers are free to use any codec they like, and the big names are split between the patent-backed H.264 and the open source Ogg Theora.

Google has added an experimental branch to the VP8 code tree, encouraging developers to begin work on the next incarnation of its newly open sourced video codec.

As you probably know, a Google I/O conference was held today and a lot of blogs said they will announce big things. And big it was: Google officially announced the release of an open source, royalty-free video format called WebM which will be using the VP8 codec Google aquired from On2 as well as Vorbis audio.
